Re: [boost] [atomic] RFC: Bitwise operations for enums

Hi,

There were quite a few times when I wanted to use bitwise operations on atomic<enum>, where the enum lists a number of flags that could be combined with bitwise AND, OR and XOR. Neither std::atomic nor Boost.Atomic enables bitwise operations for enums, so I had to resort to workarounds, such as using atomic<underlying_type_t<enum>> with explicit casts to and from the underlying type of the enum. Obviously, this is rather tedious, and I would prefer not to have to do this.

I have now implemented this in Boost.Atomic. I will be shipped in the next Boost release.
